Bob, the colors, sharpness all look good. I think the center of the flower needs to be a little more to the left (ROT) so I would crop some from the left side and if you have it, add a bit to the right side. There are a few tiny white spots that should be cloned out and I'd consider cloning or painting over that one section of white that's below and separate from the rest of the center whites. The center could stand to be brought up a bit...just enough to get the whites looking white. A few tweaks will take this way over the top!
Hi Bob, nice image overall. I like the texture and color very much. Agree with Ken on the centers placement and feel the center should be a bit more left.
The star shaped pattern is a big plus. If you lighten the center be careful about blowing the whites in the small areas since I see some detail there...
Hi Bob. Very cool blues - again. You're getting your money's worth out of these flowers. I think Ken nailed the critique so I don't have anything new to add. Just a few tweaks to make this even better. :)
